Improvements in Metal Beds, of which the following is a specification.

My invention pertains to the joints of metalbeds, such as those of the horizontal rails with the upright posts, or any others of a similar nature.

Heretofore, in joining the two pi es, tubes,

bars, or the like together, it. has een customary and usual to clamp a mold about the parts and then pour in molten metal, which when coolforms a union or enlargement encircling and fastening the two parts together. This chill casting or boss, frequently of a flower design, is objectionable because it forms a convenient place for the lodgment and retention of dust and dirt. It 18 also advantageous to do away with these enlargements because of the demand at the present time for bedsteads of extremely simple lines.

' It is, therefore, the object of my invention to avoid the use of these uniting castings, in some cases unsightly, forthe reasons specified, without diminishing or in any way sacrificilng the strength and rigidity of the bedstea I I have illustrated a number of embodiments of my invention on the aocompanyin sheets of drawings, forming a part of this specification, and on these drawings,- Figure 1 is a longitudinal section through one of the upright posts or pillars of a metal bed embodying my inventlon; .Fig. 2 is a side elevation of the end portion of a rail of the same bedstead; Fig. 3 illustrates the appearance of the joint between the two parts shown in Figs'l and 2; Fig. 4 is a hormon tal section through the joint illustrating its internal construction; Fi 5 is a longitudinal section of a modified orm of post; Fig. 6 is a similar section ofa di-fierent style of rail for use in conjunction with the pillar or post shown in Fig. 5; Fig. 7 illustrates the appearance of. the completed joint in which the two parts shown in Figs. 5 and 6 are firmly united; Fig. 8 is a horizontal section through the joint lllustrated in Fig. 7; Fig. 9 is 'a lengthwise section through a vertical post orpillar of modified ,form; Fi 10. is a side elevation of the end portion 0 a rail bar for use with the post or pillar shown in Fig. 9; Fig. 11 is a side elevation of the joint uniting the two parts shown in Figs. 9 and 10; Fig. 12 is a horizontal section just above the rail of the joint shown in Fig. 11; Fig. 13 is a longitudinal section of a still further modified form of post; Fig. 14 is an elevation of the end portion of a rail adapted for connection with the post shown in Fig, 13; Fig, 15 shows in elevation the union of the parts illustrated in Figs. 13 and 14; Fig. 16 is a section on line 16, 16 of Fig. 15, as viewed in the direction indicated by the arrows; and Fig. 17 is a horizontal section on line 17, 17 of Fig. 15.

' Referring first to the embodiment of my invention illustrated in Figs. 1 to 4, inclusive,' it will be noticed that the cylindrical tubular post 20 is provided on one'side with "lar lining 23 supplied opposite the aperture or hole 21 with a depression or indentation 24 somewhat larger than the hole 21, as is clearly shown in Fi 1. This depression forms between the limng 23 and the interior surface of the post 20 a cavity or recess 25. The hollow cylindrical rail 22, which, as stated above, is the same size as the aperture 21, is supplied near its end with a plurality of transverse holes 26 extended through its wall, and the rail is also supplied near its end with another aperture 27 through its wall. In order to unite the parts and form a tight joint between the post and rail, the end of the latter is inserted through the aperture 21 into the cavity or recess 25, and the holes 26 are so positioned in the wall of the rail that they will be within the cavity 25 after this insertion, while the aperture or hole 27. will be located outside of the post. Molten metal is then oured through the inlet hole 27, artially lin the interior of the rail 22, and flowing out t rou h the holes 26 so as to fill the cavity 25. T is body of metal 28, as is obvious, will have a head of substantial size within the cavity 25 which will be considerably larger than the hole 21, so that it can not be withdrawn therethrough. This metal is firmly fastened to the end of the rail, owing to that portion thereof which fills the holes 26. It is undera modi ed form of joint, and in this embodiment the aperture or hole 29 of the post 30 is larger in diameter than the tubular rail 31. The post 30 is equipped, as in the other species, with a lining 32 depressed'at 33 to form a cavity 34. The rail 31 is supplied at its end with holes 35 corresponding to the holes 26 of Fig. 2. It has no hole, however,

corresponding to the aperture 27. Within the rail and adjacent to its ends is inserted a plug or cap 36 which is employed to prevent the metal poured into the joint from flowing along the rail 31. To form the joint the end of the rail or tube l is inserted centrally through the aperture 29 into the recess 34, the holes 35 in these positions of the parts being within the cavity. A mold is'then clamped about the two tubes or pipes and a body of metal 37 poured into the same, the metal flowing between the rail and the margin of hole or aperture 29 into the cavity 34 and filling the same. The mold is so shaped that a neat boss 38 is formed around the rail 31 at the point where it enters the upright post. This body of metal 37, owing to the fact that the cavity 34 is larger than the aperture 29, has a head filling the cavity and thereby preventing withdrawal of the body of metal and the rail which is also securely looked to the metal 37 because the latter fills the apertures 35 and the end of the rail to the extent permitted by the internal cap or stop 36. This desi of joint is not quite so severely plain as t at of Fig. 3, but each of them has suliicient strength for all purposes.

The oint or connection illustrated in Figs. 9 to 12, inclusive, is somewhat similar to that of Fig. 7, but in this instance the square rail 39 is solid and has one or more apertures or holes 40 extended through its end. The hollow boss 41, which may be of any desired shape or contour in cross-section has through one facean aperture i2 greater than ,the cross-section of the ram 39, and the post is also supplied, as in the other instances, with a lining 43 equipped with a depression 44 opposite the hole 42. to limit andrestrictthe flow of metal into the post. The end of the rail is inserted centrally in the aperture 42 and is pushed in far enough so that the hole or transverse aperture 40 of the rail is within the cavity between the depression 44 and the.

interior surface of the post. A mold of suitable shape is clamped about the parts and the metal poured in as described above, the

mold being so shaped as to produce a boss 45 around the end of the railand' next to post or pillar.

I have shown in Figs. 13 to 17, inclusive,

the

another style of joint in which the post 46 pression or indentation 50, is of substantially U-shape incross-section and does not pass completely around the interior surface of the post. The end of the rail has oneor more holes 51 extended through its walls, and the interior of the rail, as in the case of the rail shown in Fig. 6, is equipped with an internal plug or stopper 52 to limit the flow of metal into the rail. about the two parts, as in the case of the joint shown in Fig. 7, and the finished joint has a boss or enlargement 53 about the end of the rail.

In each of these cases it will be-observed that the body of anchoring metal has a rather large head within the pillar or post whereby to secure a firm and rigid connection therewith, the metal being secured to the end of the rail by filling the apertures of the latter.

Although I have shown and described a number of forms of joints, each of which embodies my invention, these are merely sugestive of a considerable number of such oints which-would fall within the spirit and essence of my invention. It is, therefore, to be understood that my invention is not limited to the precise structural details shown and described, but is susceptible of a variety of embodiments, and that many minor mechanical changes may be made in the joints shown and described without departure from the substance of my invention or the sacrifice of any of its benefits and advantages.
